<p>To isolate at least one unsaturated fatty acid with sixteen or more carbon atoms in the molecule and/or at least one compound of a fatty acid of this type from a mixture, in particular vegetable or animal, of fatty acids and/or fatty acid compounds, the fatty acids and/or fatty acid compounds in the mixture are passed, directly or after a reaction, in a mobile phase composed of supercritical or liquid carbon dioxide in a column over a stationary phase which has, on a basic framework, a coating of a phase which has at least one free electron pair on at least one group in its molecule or molecules and/or which has at least one multiple bond in its molecule or molecules, and at least one fatty acid and/or fatty acid compound which is to be isolated is, after the saturated fatty acid or fatty acid compound with the same number of carbon atoms has, if present, passed through the column, collected as such or in a concentrated mixture. <IMAGE></p> |
